" I Si JAMES I-I. REMINGTON, OF WAUKESHA, WISCONSIN.

PRIMING- COCK.

Application led October 19, 1920.

To all whom t may concern:

Be it known that I, JAMns H. REMINGTON, a citizen of the United States, and resident of Vaukesha, in the county of Waukesha and State of Wisconsin, have invented certain new and useful Improvements in Priming Cocks; and I do hereby decla-re that the following is a full, clear, and exact description thereof.

This invention relates to priming cocks for internal combustion engines, and more particularly the type that provides for effecting a closure of the cup portion to prevent the acoummulation of dust, oil, and dirt, which upon opening of the valve would be carried into the` cylinder.

The invention has for its object to provide a cock of this character that can be manufactured at comparatively low cost and which shall be strong and durable -in construction. To attain this, my invention consists of a cock having a combined valve and cup whereby the casing forms a closure for the cup when the cock is closed. It further consists in a novel arrangement whereby a housing is provided for enclosing the spring, thereby rendering a neat appearance to the cup and at the same time, permitting the use of a comparatively large spring which will not deteriorate as quickly with wear.

In the drawings,

Figure l is a longitudinal central section of la priming cock, embodying the function of my invention,

Figure 2 is a side elevation, and,

Figure 3 a plan view.

Referring more particularly to the accompanying drawings, l designates a casing of a priming cock provided with an inlet port 2 and an outlet port 3, As is customary in cocks of this character, a valve member 4 disposed within the casing is slightly tapered to insure a tight iit, and has disposed between a washer 4C mounted upon its reduced end 5 an expansile spring 6. EX- tending laterally from one side of the casing is a housing 7 adapted to surround the spring 6 and having its end closed by the washer 4. The valve Il is further provided with an enlarged cup portion 8 adapted to communi- Serial No. 417,864.

cate with the outlet port 2, and also a reduced passage 8 forminga communication between the cup portion 8 and the outlet port 3. It will be noted that in order to have a suitable size cup portion formed within the valve member, the same must necessarily be of comparatively larger diameter than customarily used in valves of this type. This gives an added advantage in'that the wearing surfaces between the valve and casing are greatly increased, thereby reducing wear between these members. It also permits the use of a comparatively large .spring which is less liable to deteriorate with wear than the small spring that is customarily used on cocks of this kind.

It is further obvious that by my construction,'I have not only reduced the cost of manufacture by the elimination of the cup from the casing, but I have also done away with the necessity of providing an eXtra closure or cover for the cup.

, In addition to these advantages, I have constructed a cock which is not only symmetrical, compact and neat inappearance, but is also of a strong and durable construction.

I claim:

l. In a priming cock the combination of a casing having an enlarged inlet port and a small outlet port, a truncated conical valve for controlling said ports, said valve being provided with an enlarged inlet opening and a small outlet opening, both of said openings registering simultaneously with said ports, a housing extending from said casing, an extension on said valve, a spring surrounding said eXtension, means on the ends of extension for closing said housing, said spring contacting at one end with said means and at the other end with said casing for retaining said valve in snug fitting engagement with said casing.

2. In a priming cock, the combination of a casing having an enlarged inlet port and a small outlet port, a handle, a truncated conical valve integral with said handle for controlling said ports, said valve being provided with an enlarged inlet opening and a small outlet opening, both of said openings registering simultaneously with said ports, a housing extending from said casing, an extension on IOC said valve, a spring surrounding said extension, a washei` on the end ot said extension 'for closingthe end of said housing, a pin on sai-d extension for limiting the movement of said Washer, said spring contacting at one end With said Washer and at the other end with said Casingl for retaining said valve in snug tting engagement with `said easing.
